MIMO System Simulation with BPSK Modulation and Rayleigh Channel for Eb/No-BER Performance Analysis

This MIMO system simulation employs Binary Phase Shift Keying (BPSK) modulation and operates under Rayleigh fading channel conditions to generate Eb/No versus Bit Error Rate (BER) performance curves. The simulation framework involves transmitting BPSK-modulated signals through multiple antennas, applying Rayleigh channel modeling to simulate realistic wireless propagation effects, and systematically varying the signal-to-noise ratio (Eb/No) to measure corresponding BER values. Key implementation aspects include: - BPSK modulation/demodulation using constellation mapping with ±1 symbols - Rayleigh channel modeling with complex Gaussian random variables for fading coefficients - MIMO signal processing with maximum ratio combining or zero-forcing equalization techniques - BER calculation through Monte Carlo simulations comparing transmitted and received bits - Performance curve generation by sweeping Eb/No values typically from 0 dB to 20 dB The resulting BER curves provide crucial insights into system robustness, diversity gain, and error performance under various channel conditions, serving as fundamental metrics for wireless communication system design and optimization.
